Abstract

The invention discloses an oil-immersed capacitor unit structure for a locomotive roof, and the structure comprises a capacitor core. A U-shaped auxiliary package is disposed on the left side surfaceof the capacitor core, and two ends of the auxiliary package respectively extend to the front and rear side surfaces of the capacitor core after the auxiliary package wraps the left side surface of the capacitor core; a connecting sheet A is located at the outer side of the auxiliary package, and the auxiliary package isolates the connecting sheet A from the capacitor core; an outer package is wound outside the auxiliary package; the connecting piece A is wrapped inside the outer package, and the periphery and the bottom of the capacitor core are wound by the outer package; a filling paperboard and an auxiliary outer package are sequentially wound between the outer package and the capacitor shell; and the periphery of the capacitor core is wrapped by the filling paperboard and the auxiliary outer package. The problems that the capacitor bears high-voltage and high-strength vibration in the running process of a locomotive and a signal of a certain channel needs to be filtered out in therunning process are solved.

Description

technical field [0001] The invention belongs to the technical field of power capacitor units, and relates to an oil-immersed capacitor unit structure for a locomotive roof. Background technique [0002] The capacitor is composed of several parts such as the core, the shell, and the outlet porcelain sleeve. There are hanging plates on both sides of the box wall for installation, and the grounding bolts are installed on one side of the hanging plate. The shell is formed and welded by stainless steel plates. [0003] The rated voltage of a single capacitor commonly used in domestic substations is generally <10kV, and the withstand voltage between terminals is 2.15U N , there is no special requirement for the anti-seismic performance of a single capacitor. The unit voltage of the capacitor used on the locomotive roof is 40kV. During the operation process, the signal of a certain frequency band needs to be filtered out, and it must be able to withstand high voltage and vibrati...
